Potato Biscuit

Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Potato Biscuit

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Make the dough

  1. Heat the milk and water in a pot.

  2. Add the butter, sugar, and salt when warm.

  3. Stir in the mashed potato mixed with the egg.

  4. Add enough flour to form a stiff dough.

  5. Mix in the yeast and let the dough rise.

Shape and bake

  1. Shape into biscuits and let them rise again.

  2. Bake in a moderate oven at 350°F (175°C).

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Forms the stiff dough structure that holds the biscuits' shape.
Yeast
Produces gas as it ferments, making the dough rise and become light.
Egg
Binds the mashed potato into the dough and adds richness and structure.
Mashed potato
Adds moisture and tenderness to the dough.
Butter
Adds fat, softening the crumb and contributing flavor.

The step that matters

Letting the dough rise. Yeast needs time and warmth to produce enough gas for the dough to rise properly. Rising too short leaves biscuits dense, while over-rising can make them collapse.

Swap the potato

How well each one fits the dish's main ingredients (milk, butter, sugar, egg, flour):

  1. Sweet potatofits about as well
  2. Leekfits about as well
  3. Arrowrootfits about as well
  4. Potatothe original

Fit is the average pairing score against milk, butter, sugar, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
